Please look at

MdeModulePkg/Include/Library/BootLogoLib.h
MdeModulePkg/Library/BootLogoLib/*
MdeModulePkg/Logo/LogoDxe.inf

and follow wherever those lead.

LogoDxe contains the image and exposes the custom protocol.

BootLogoLib lets your PlatformBootManagerLib instance consume (display)
the image via the protocol. You need to call the BootLogoLib functions
in your platform BDS code so the logo be displayed.

(Sorry, got no time to investigate / elaborate more in depth.)
